No matter if it's local or remote, CD-R/W need packet writing on the UDF filesystem.

I think there is now a Linux UDF driver you could peek at to see how the UDF filesystem works. Then you'd need to know how packet writing works, and learn SPTI to actually use it...

If you do it for a remote computer, you'd in addition most probably have to write your own network protocol and service.

Hi Mike,
Many thanks for your reply. Correct me if I'm wrong, but, as the CD's will always be formatted for direct R/W (i.e. will accept Explorer drag-and-drop operation), the actual mechanics of file-writing on the CDROM drive is not the issue, surely. I "assume" that I will be able to use the CopyFile() function if I can find out what the filepath (via DCC) of the remote CDROM drive is. Alternatively, if I knew how to emulate a drag-an-drop operation programatically within my program on the local computer's DCC window of the remote computer's sharable drive icons (I can do this manually !) then this would solve my problem. Any advice on either of these approaches would be greatly appreciated. Big Grin | :-D

That means you already have an R/W UDF driver and packet writer on the machine handling the CD-R/W.

You however only mention Explorer operations. What happens if you try to copy a file from a CMD.EXE shell (still only locally on the machine that has the CD-R/W) to that CD-R/W disk - does that work? If it does, then you're in a better seat to make the whole idea work. If not, you'd be back to (almost) square one I think.

If it doesn't work, I wouldn't be too surprised if that stuff is implemented by this particular vendor as an Explorer shell extension... You judge how easy and/or "fun" it would be to try to interact with it.

I "assume" that I will be able to use the CopyFile() function if I can find out what the filepath (via DCC) of the remote CDROM drive is.

I seem to recall that "assumption is the mother of all fsck-ups". Smile | :)

This often is even more true when dealing with Microsoft APIs and other creations.

Hi Mike, I can confirm that in a DOS window I can copy files to the CDROM drive. As I've said before, my main issue is with interacting programmatically with the DCC window on the desktop which contains the remote drive icons. Do you know the details of how I can do this ? Confused | :confused:

Thanks for your help.

i know that ow to register a dll. i want this feature automatic. ok letme explain this again.

I have a dll suppose my.dll which performs a specific function. I want this DLL as a package so that i can distribute it to different clients.

I can make the package but the problem is that i don't want them to run regsvr32 to register the dll. I want this during the setup time.

i hope now my problem is clear..

awaiting replies..any ideas are appreciated.

thanks in advance..
cheers.

You have several options
1. Microsoft MSI
a. Use VC7 to create setup
b. Use InstallShield to create MSI installation
c. use Wize to create MSI installation
2. Create CAB file
a. Use VC7 to create setup
b. Use InstallShield to create CAB File(I am not sure new IS supports it)
c. use Wize to create CAB installation
3. Use WinZip self extracting capabilities
4. create .bat file

The keywords to search on MSDN : MSI, CAB, install
The keywords to search on Internet : Installshield, Wize, WinZip

add-ins in c++ using the DTE-object

Alex gave you great alternatives, but it boils down to this: your setup program should give you the option to automatically register COM DLLs once they're installed. If it's your own home-grown setup program, then can either execute regsvr32 or load the DLL and then call its DllRegisterServer procedure.

Sub DocumentsExample()
MsgBox(DTE.Documents.Count)
End Sub

How can i get this DTE object? the compiler doesent recognises it.

I would like to make an addin for VC++.NET in which i can manipulate the code. (textmanipulations)
can anybody tell me, how i can do this? i dont know how to do things which i coud do in VB with
activedocument.selection , etc..

thanx for any input!!!

can't understand what ur looking for..but what i can make out is you want to messgae something on the screen.. for that u just have to write

MessageBox(CString);
or MessageBox("string");

so you need to convert whatever you want to display into string first then you can display anything.
hope you can slove it now..
cheers..

hy, thanx for the answer.
unfotunately, its not what im looking for.

1. MessageBox("string"); gives a compiler error,
only : MessageBox(NULL, _T("Hello From C++"), _T(""), MB_OK) is ok.

2. i wonder how to use the DTE object. in the MSDN library the example code is all in VB!

3. remember, i try to program an add-in !

It would help if we knew what this DTE object is. More importantly, search for the type-library. Once you find it, you can use the Class Wizard/Automation tab to add a wrapper class for it which you can then use in your code.

DDX and DDV with variables gives a parsing error...

Joan M14-Jan-03 23:54

Hello,

1. I need to monitor that the user has entered values that are in range.
2. There is only one editControl that is used in order to enter values for 4 different things.
3. The DDV that I've placed is equal thatn the normal one but I've changed the maximinum allowed value to a variable in order to make it more flexible and capable to adapt to each maximum value.

This is what I've done:

DDX_Text(pDX, IDC_ED_POSICIO_DESTI, m_veddPosicioDesti);
DDV_MinMaxDouble(pDX, m_veddPosicioDesti, 0., this->m_EixSeleccionat.m_MovimentEixDirecte.m_dPosicioMaximaPermesa);

but the problem is that when I enter the Class wizard (Ctrl+W) I receive this message:

Parsing error: Expected ")".<br />
Input Line: "DDV_MinMaxDouble(pDX, m_veddPosicioDesti, 0., this->m_EixSeleccionat.m_MovimentEixDirecte.m_dPosicioMaximaPermesa);"

What can I do in order to avoid that message?

Thank you in advance.

your getting theproblem because you place the DDX_... command within the //AFX_DATA comment blocks. These are the lines that class-wizard will parse during the load phase. If you move the line outside of the comment block, then class-wizard will be happy.
